Title: Phosphoric acid type fuel cell
Inventor: IYASU KYOTARO
IPC: H01M8/04
Filed: 1988-03-24
Abstract: PURPOSE:To make it possible to remove phosphoric acid without pressure loss owing to a clogging by making the surface area per unit volume of a metallic wool at the anode side scrubber larger than that at the cathode side scrubber. CONSTITUTION:A metallic wool is filled to make the surface area per unit volume of the metallic wool in the scrubber 8a at the anode side larger than that in the scrubber 8b at the cathode side. By passing the cathode side exhaust gas through the cathode side metallic wool 9b which is filled to make the surface area per unit volume small, the phosphoric acid is removed. Since the surface area is smaller there, the reaction is little and the reaction product is also little. As a result, even though the metallic wool is reacted at the maximum with the phosphoric acid, under the presence of oxygen, almost no clogging is generated. On the other hand, the anode side exhaust gas in the reduction atmosphere passes through the anode side metallic wool 9a which is filled to make the surface area per unit volume large to remove the phosphoric acid. Since the surface area is larger there even though the reaction speed is somewhat slower than in the cathode side, the phosphoric acid can be removed perfectly.

Title: Linear actuator with dustproof mechanism
Inventor: YANAGISAWA TAKESHI
IPC: F16C29/08
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To prevent dust generated in a linear actuator from leaking out through opening parts formed along a moving locus of a moving stage, in a linear actuator. SOLUTION: A housing 2 of this linear actuator 1 has a box shape, and opening parts 27, 28 are formed on the upper surface of it along moving loci of projecting parts (connecting parts) 44b, 44c of a moving stage 4. The opening parts 27, 28 are closed by dustproof belts 29, 30 arranged inside the housing. Rollers 61 to 66 for detouring respective belt 29, 30 to sides in the housing are attached on the moving stage 4 so that respective belts 29, 30 may not interfere with the projecting parts of the moving stage. The opening parts 27, 28 are reliably closed by the dustproof belts 29, 30. Air suction is performed from outer suction ports 8a, 8b arranged near the opening parts 27, 28 and from suction ports 22b, 23b arranged in the opening parts to reliably prevent dust generation from the linear actuator.
